The only info written on the label is what's in my original post. I agree that this doesn't sound exactly like the Nation Devotions, that was just the group named that that sounded the most similar, at least that I could find. It's such a generic name for a group that it could be anybody or nobody, really. If it helps put it in context, this came from the estate of a guy who worked in studios, film, TV, commercials, industrials, etc decades ago, and I also found an acetate of the record below, but with a different, presumably unreleased b-side. Now, what this guy's involvement with both records was, I don't know.
